B25: Cytomegaloviral disease

Cytomegaloviral disease, commonly known as CMV, is an infection caused by the cytomegalovirus, a type of herpesvirus. This virus is generally transmitted through direct contact with bodily fluids such as saliva, urine, blood, or through sexual contact. It can also be passed from a pregnant woman to her baby during pregnancy or childbirth. Many people with CMV might not experience any symptoms, but some may develop flu-like symptoms, including fever, sore throat, fatigue, and swollen glands. In people with weakened immune systems, such as HIV/AIDS patients or organ transplant recipients, CMV can cause more serious illnesses affecting systems like the retina of the eye, the digestive tract, the lungs, or the brain. Disease progression can range from mild and temporary to severe and long-lasting, depending on the patient's overall health and immune status.
